Cage units contain all of the working parts of a thermostatic steam trap, including the seat, within a stainless steel housing. Cage units are one-piece, stand-alone, fully-removable units. This allows for removal and testing of the element outside of the original trap body. No special tools needed for installation. Cage unit are available for a wide variety of makes, styles, and sizes of thermostatic steam traps for low, medium, and high pressure service.

Float and thermostatic (F&T) steam traps are found at the end of steam mains, long piping runs, and steam heating equipment that produce large quantities of heat such as unit heaters, heat exchangers, etc. Composed of a valve mechanism assembly with seat, internal thermostatic air vent and a stainless steel float. F&T traps work well on both light and heavy loads of steam heat generated condensate. These traps are meant for low-pressure (15 psi or less) steam heating systems as well as higher steam pressures up to 175 psi. F&T traps feature separate orifices for condensate and air, which provide continuous condensate drainage and air venting even under conditions of zero pressure. A level connects the ball float to the valve and seat. Once condensate reaches a certain level in the trap, the float rises, opening the orifice and draining condensate. A water seal formed by the condensate prevents live steam loss. Since the discharge valve is under water, it is not capable of venting air and non-condensables. When the accumulation of air and con-condensable gases causes a significant temperature drop, a thermostatic air vent in the top of the trap discharges them.

Inverted bucket traps are robust, long-lasting mechanical steam traps found in both steam heating systems and industrial applications. Inverted bucket traps are composed of a stainless steel bucket, valve mechanism assembly and seat, and cover gasket. Inverted Bucket steam traps rely on the difference in density between steam and condensate to drain condensate as it forms. This keeps the steam space free of condensate to provide maximum system efficiency. Inverted Bucket steam traps rely on the difference in density between steam and condensate to drain condensate as it forms.

State Supply offers liquid drain traps from several different manufacturers, such as Armstrong and Spirax-Sarco. Liquid drain traps remove liquids from gases compressed air systems in industrial applications. The trap drains off the water while preventing the escape of compressed air. They are available in pressures from 75 to 150 psi and 1/4", 3/4", and 1" pipe sizes.

State Supply offer radiator steam traps from several different manufacturers, such as Armstrong and Mepco. Radiator steam traps are found on radiators, convectors, and related equipment in steam heating systems. Usually operating under 15 psi of steam or less, radiator traps often make up the largest population of steam traps in your low-pressure steam heating system. The single operating component within the radiator trap is a thermostatic element which opens to let condensed steam out and closes to prevent steam from going beyond its point of use. Radiator traps are available in several different connection sizes and operating pressures.

State Supply offers thermodynamic steam traps from several different manufacturers, such as Illinois and Spirax-Sarco. Thermodynamic steam traps are found on tracer lines and process equipment in industrial-like applications. The single operating component within the thermodynamic steam trap is the disc. These traps are available in several different pipe connection sizes.

State Supply offers thermostatic industrial steam traps from several different manufacturers, such as Spirax-Sarco. Thermostatic industrial traps are recommended for high pressure, sterilizers, laundry and kitchen equipment, process equipment, and large mains where air handling is critical. They handle steam, air, and condensate by pressure and temperature to open and close the diaphragm or bellows. This thermostatic element expands when steam is present to close the trap and contracts when the cooler air or condensate is present to open the trap which allows the condensate to drain. The Spirax-Sarco thermostatic trap has cast iron body available in angle or straight pattern.

State Supply offers steam trap testing tools and steam trap testers monitor your steam system. Steam traps have an operational life ranging from four to eight years and often fail in the open position, allowing steam to escape its point-of-use. Steam trap testers allow you to know if your steam traps have failed. Choose from ultrasonic listening, temperature sensing, and electronic stethoscope instruments.
